Many household refrigerators have a fresh food compartment above a freezer compartment, commonly known as a bottom mount refrigerator. Bottom mount refrigerators normally do not have an ice dispenser in the doors for the fresh food compartment, since ice is normally made in the freezer compartment and would have to be transported upwardly for dispensing. Recently, bottom mount refrigerators have become available with an ice maker in the fresh food compartment and an ice dispenser in the door. Some of these newer bottom mount refrigerators also include a water dispenser in the door of the fresh food compartment. However, the water tank and filter for these newer refrigerators are mounted in the side or rear wall of the fresh food compartment, which takes up valuable food space, and creates a displeasing aesthetic appearance. Furthermore, during installation of the water system, the tank and filter manifold are normally installed as separate components within the fresh food compartment, which has limited space for making the plumbing connections. The confined space results in increased assembly and installation time.
Therefore, a primary objective of the present invention is the provision of an improved bottom mount refrigerator having a water system mounted in the ceiling so as to maximize the space in the fresh food compartment.
Another objective of the present invention is the provision of a bottom mount refrigerator having a drop ceiling for hiding a water tank and filter mounted above the ceiling.
Another objective of the present invention is the provision of a bottom mount refrigerator having a bracket subassembly supporting a water tank, filter, valve, and light source for pre-assembly before installation of the bracket in the refrigerator compartment.
Still another objective of the present invention is the provision of a water storage tank in the ceiling of a refrigerator oriented horizontally, with an outlet which minimizes the air in the tank.
Yet another objective of the present invention is the provision of an improved bottom mount refrigerator having a water system which can be quickly and easily installed in the top of the fresh food compartment and hidden by an aesthetically pleasing false ceiling.
These and other objectives will become apparent from the following description of the invention.
The present invention is directed to a bottom mount refrigerator having a water system and lighting system pre-assembled on a mounting bracket for installation in the top of the refrigerator fresh food compartment. A false drop ceiling covers the water system, lighting system, and mounting bracket to provide an aesthetically pleasing appearance inside the fresh food compartment. The ceiling includes a pivotal filter cover moveable between open and closed positions to provide access to the water filter, a tank cover for hiding the water storage tank, and a removable light cover to provide access to the light source. The false drop ceiling defines a space for housing the bracket, water system components, and light system between the liner and the ceiling. A fašade extends across the front to cover and hide the space and provide improved aesthetics. The water filter manifold, filter cartridge, water storage tank, valve, thermostat, light fixture, and wiring harness are pre-assembled on the mounting bracket, which can then be installed in the roof of the fresh food compartment. Then, the false ceiling can be installed, followed by the covering fašade.
A bottom mount refrigerator 10 is shown in
An insulated liner 20 is provided in the fresh food compartment 16, and includes a top wall 22, a bottom wall 24, opposite side walls 26, and a rear wall 28. Shelving (not shown) is installed to the liner 20 in well-known manners to support food and beverage items.
An ice making compartment 30 is provided at the top of the fresh food compartment 16 adjacent the top wall 22 of the liner 20. The door 12 includes an interior ice storage compartment 32 which is in communication with the ice making compartment 30 via aligned openings 34, 36 in the ice storage and ice making compartments 30, 32, respectively, when the door 12 is closed. An ice dispenser 38 is provided on the outside of the door 12. The door 12 also includes a water dispenser 40, which dispenses water in a conventional manner.
The present invention is directed towards the water and lighting systems of the refrigerator 10, both of which are mounted at the top of the fresh food compartment 16 so as to maximize useable space in the compartment 16. More particularly, the top wall 22 of the liner 20 includes a recess for receiving a bracket or panel 44, which supports the water and lighting systems for the refrigerator 10. The bracket is best seen in
The water system for the refrigerator 10 is mounted to the bottom or lower surface of the bracket 44, as best seen in
The filter manifold 50 includes a body 60, with a pair of pins 62 extending from opposite sides so as to define a pivot axis. The pins are received in recesses 64 in the bracket 44 and are retained in any convenient manner. For example, in a preferred embodiment, one of the pins extends into a hole in the wall 66, while the opposite pin is snap fit beneath a tab 68 so that the manifold 50 is pivotally mounted to the bracket 44. The filter cartridge 52 is mounted to the manifold 50 by threads or twist block action, as is known in the art. A water inlet line 70 supplies water from a water source (not shown) to the manifold 50 and the cartridge 52. A water outlet line 72 delivers filtered water from the filter manifold 50 to the water tank 54.
The water tank 54 is preferably tubular, extending in a serpentine path, as seen in
The outlet line 78 is connected to the inlet of the valve 56, as best seen in
The thermostat 58 is mounted to the bracket 54 via a snap fit of the thermostat body between a pair of upstanding legs 90, as seen in
The bracket 44 also supports the light assembly or fixture 92 for the fresh food compartment 16 of the refrigerator 10. The lighting system 92 includes one or more fixtures, such as incandescent bulbs or LEDs 94. The lighting system 92 is retained on the bracket 44 by tabs 96 which overlap the perimeter edge of the lighting fixture. A wiring harness 98 for the lighting system extends through a channel 100 in the bracket 44 and includes a plug 102 for quick and easy connection to the electrical system of the refrigerator 10.
As seen in
The present invention also includes a false ceiling 112 for covering the mounting bracket 44 and the components mounted therein. The ceiling 112 includes a tank cover 114, a pivotal filter cover 116, and a light cover 118. The tank cover 114 supports the filter cover 116 and the light cover 118. The light cover 118 is transparent or translucent to permit illumination of the fresh food compartment 16 by the lighting fixture 92 when one or both of the doors 12, 14 are open.
The tank cover 114 includes a pair of tabs 120 on the rearward edge which are received in corresponding openings in the back wall 28 of the liner 20. The front edge of the tank cover 114 has a pair of bosses 122 (
The filter cover 116 is pivotally mounted at its rearward end to the tank cover 114. As seen in
The light cover 118 is snap fit at the rear edge to the tank cover 114 via tabs 140, shown in
Thus, the false ceiling 112 constitutes a drop ceiling defining a space between the top wall 22 of the liner 20 and the ceiling 112 for housing the water and light systems for the refrigerator 10. The space or gap between the ceiling 112 and the top wall 22 is covered by a fašade 148 extending across the width of the fresh food compartment 16. The fašade 148 includes an opening 150 through which ice is delivered from the ice compartment 30 to the ice storage compartment 32 in the door 12. A door or flap 152 is pivotally mounted to the fašade 148 so as to move between open and closed positions relative to the opening 150, when the door 12 is opened and closed, respectively. The movement of the flap 152 is controlled by a lever 154 extending through the fašade 148. The lever 154 is engaged by the door 12 when the door is closed, so as to open the flap 152, and disengaged from the door 12 when the door is open, so as to close the flap 152.
The fašade 148 is mounted to the liner 20 and to the false ceiling 112 by a plurality of tabs 156, 158, respectively, as best seen in
It is understood that the various mounting connections for the bracket 44, the water and light systems, the false ceiling 112, and the fašade 148 may be modified from those shown in the drawings and described above, without departing from the scope of the invention. The mounting connections also may be moved to other locations to facilitate manufacturing and assembly.
In another aspect of the present invention, an improved assembly method is provided. The water filter assembly 50, 52, the water tank 54, the valve 56, the thermostat 58 and the lighting fixture 92 are pre-assembled on the bracket 44. Then the bracket 44 with the water and lighting systems is secured to the liner 20. The plumbing and electrical connections are then completed for the refrigerator 10. Next, the false ceiling, without the light cover 118, is installed. Then, the fašade is attached. Lastly, the light cover 118 is installed by inserting the front edge above the lens 162 and then snapping the back edge into the tank cover 114. Thus, the ceiling 112 and fašade 148 provides a clean, smooth aesthetic appearance for the fresh food compartment 16.
The invention has been shown and described above with the preferred embodiments, and it is understood that many modifications, substitutions, and additions may be made which are within the intended spirit and scope of the invention. From the foregoing, it can be seen that the present invention accomplishes at least all of its stated objectives.
